Elastic Container Registry (ECR) for example supports Tag Immutability (TI). TI implies that docker tags cannot be overwritten if they exist in a docker-registry.
The settings of the organization and the ones from a repository were inspected, but no TI setting was found.
Questions
- Does quay support TI?
- If true, how to enable it
- If false, how do you or does your organization prevent that tag overwrite takes place?
